The manufacture of gears is a field of particular competence within the Hilchenbach workshop of SMS group. Here, gears are designed, toothings milled and ground, housings welded and finally complete units are assembled, all under one roof. This potential could recently be demonstrated with the production of a four-stage gear with totally 29 wheels and a weight of 261 tons. This radial gear for a forging machine is the most complex one ever made in the Hilchenbach workshop.
|Performance||4 x 1,500 kW = 6,000 kW|
|Rated output torque||8,805,000 Nm|
|Total gear ratio||115.3:1|
A stand-out feature of our Hilchenbach and Mönchengladbach locations is the direct interaction between engineering and manufacturing. This naturally facilitates a continuous exchange of ideas between these departments for ongoing optimization of our products.
In the pre-assembly phase, the contact pattern of the gearwheels was continuously checked to ensure fast and precise installation at the customer’s site.
After pre-assembly, the gear was dismantled into smaller units and prepared for transportation. The challenge here was to forward the largest part, with a total weight of still 193 tons and a volume of 88.3 m³, to the Port of Hamburg for shipment.
Together with the transport service provider DAHER PROJECTS GmbH, and thanks to a detailed agreement with Deutsche Bahn, this challenge was also successfully overcome.
The workshop in Hilchenbach has its own rail siding, meaning the parts could be easily transported by train. This will play an increasingly important role for the location in future as a reliable alternative to road transport.
